(Sorry another new Mac owner question!) I've just bought an iMac, installed Boot Camp + Win 7. Everything works fine. I'm looking at purchasing Parallels so that I can also run the Windows partition virtually and to create an image of my old Win XP machine. I've seen that available are "Parallels Desktop 6 for Mac" and "Parallels Desktop 6 Switch to Mac Edition". But what are the differences? I've seen that the switch to Mac edition contains a USB-USB cable (but these can be bought cheapily). Are there other features allowing me to create Windows images from old machines that are exclusive to that edition or is the cable the only difference (except of course the price difference)?
